CVE-2026-31459

CVE-2026-31459 affects the Linux kernel DAMON_SYSFS path. The vulnerability is a memory leak: when damon_sysfs_new_test_ctx() fails inside damon_sysfs_commit_input(), param_ctx is leaked because the cleanup at the out label is skipped. The patch series “mm/damon/sysfs: fix memory leak and NULL de...
